摘要：

Degradation behaviors, particularly for the increase in spectral linewidth and FM efficiency, in 1.55-mu-m long-cavity MQW DFB lasers, with a spectral linewidth of around 1 MHz, are presented from the viewpoint of coherent system application. Through the clarification of the behaviors, it is shown that highly coherent lasers are sufficiently durable in coherent transmission systems.
